IMPROVEMENT IN FLUTlNG-MACHINES.

Specification forming part of Letters Patent No.

217,670, dated July 22, 1879; application filed May 14, 1879.

To all whom it may concern:

Be it known that I, GARRET ADREANCE, of Brooklyn, in the county of Kings and State of New York, have invented certain Improvements in Flirting-Machines, of which the following is a specification.

This invention relates to that class of machines known as chain-fluters and it consists, in part, of a hood for guiding and retaining the fluted goods on the chain, and, partly, in the peculiar construction of the bearings in which the rollers are mounted.

In these machines, as ordinarily constructed, the chains which form the plaits are left uninclosed, and when the goods have passed beyond the rollers and the links open the fluted goods leave the chain.

My invention seeks to retain the fluted goods between the heated links ofthe chain for a longer period, so as to make the flutes or corrugations more permanent. Moreover, in the employment of heat for fluting, the journals of the rollers become hot, are covered with smoke, and rapidly dry up the oil, which, with the smoke, forms a thick crust, impeding the operation of the machine by reason of the friction produced. This crust must be removed frequently, and in the ordinary mounting of the journal its removal is diflicult of accomplishment.

My invention seeks to obviate the difiiculty by means which will be fully hereinafter described.

In the drawings, which serve to illustrate my invention, Figure l is an end elevation of a flirting-machine embodying myinvention. Fig. 2 is a plan or top view of the same. Fig. 3 is a partial sectional elevation of the machine on a larger scale. Fig. 4 is an elevation of a modification of Fig. 1

A A represent the end frames, and a a the stretchers which tie them together. B is the upper, and O the lower, of the endless chains, formed of the usual crimping-links. These are borne by four rollers, those in front being provided with intermeshin g gear-wheels b b and a crank,D, and those behind being journaled at c c in adjustable bearing-blocks E, provided with set-screws or adjusting-screws d d. The blocks E are cut entirely away at the back of the journals 0 0, (see a: m, Fig. 1,) and the lat- I ter press only against the front side of the bearing, leaving ample clearance behind for the accumulation of crust from the burned oil. This construction also gives free access to the journal in scraping, cleaning, and oiling it.

F is a guiding-hood and keeper arranged over the top of the upper chain, B, its rear edge curving over the rear upper roller, and arranged substantially concentric therewith, the margin eresting close to the point or line where the intermeshing links of the chain begin to open as they break around the upper and lower rollers, as shown in Fig. 3.

The strip of goods to be fluted is fed between the chains at the front, and is carried through by the rotation of the crank to the rear side. WVhen the end of the strip reaches the point where the links begin to separateby breaking around the rollers it escapes from the chain and tends to drop. The curved margin of the hood prevents this and directs it upward, keeping it in the chain as it passes around the upperroller, and until the links again close up on the returning upper side of the upper chain. It now passes back under the level or flattened portion of the hood, which may be made to fit down closely to the chain, as shown. By means of this hood, the goods or materials are kept in close contact with the heated links of the chain twice as long as when no hood is employed, and the flutings are rendered far more permanent thereby.

The hood F may be hung or hinged in various ways, that shown in Figs. 1 and 2 being perhaps preferable. In this construction G is a bar, to which the hood F is secured by screws ff, the holes through which they pass being slotted to allow for some adjustment in setting it. This bar G has uprights, one of which is prolonged to form a handle, 9, and the other, g, provided with two bevels, which take under a spring, h, fixed to the main frame. The whole swings on a rod, 1', which extends across the frame through the uprights g g, and has hearings in the frame 5 or, if preferred, a pin or stud on each side frame may be substituted, or any other suitable method of pivoting employed. When the hood is down or in its normal position the spring h presses upon one of the flattened or beveled faces and retains it in position, and when turned back, as indiblocks E, in which case it will always adjust itself with the said blocks and retain its rela tive position with respect to the chain-rollers "and chain, whatever may be. the adjustment of the blocks.

The hood F is shown as constructed of a plate, but it maybe composed of curved wires or of an open-work plate. These openings should not, however, be wide enough or large enough to allow the fluted goods to pass through.

H H are hinged covers, \vhich'turn up over the bearings in the blocks E, and protect them from the smoke of the burner which heats the chains.

I claim- 1. A chain-fluting machine provided with a hood or keeper, F, for the purposes set forth.

.fivhere it breaks over the rear roller, so as to prevent the crimped goods from escaping from the chain, and arranged to be turned back, substantially as set forth.

3. The combination of the swinging hood or keeper F, the bar G, the handle or lever g, the beveled upright g, and the spring h, all constructed and arranged substantially as set forth.

4. The combination of the adjustable hood F with the adjustable bearing-blocks E E and the chains and rollers of the fluting-machi-ne, substantially as set forth.

5. In a chain-fluting machine the blocksE E, provided with slotted bearings as a: for the journals 0 c of one pair of chain-rollers, in combination with the chains B 0, their carryingrollers, the stretching-screws d d, and the pro tecting-covers H H, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

GARRET ADREANGE.
